NOTE-SHEET MUSIC-DISK.

SPEGlFICATIGN forming part of Letters Patent No. 696,910, dated April 1, 1902.

Serial No. 57,054. (No model.)

To (all whom, zit ntcty concern:

Be it known that I, Josnrn NATTERER, a citizen of the United States, residing in Jersey City, Hudson county, New Jersey, have invented certain new and useful Improvements in Note-Sheets or Music-Disks, of which the following is a specification.

This invention relates to note-sheets or music-disks for use in music-boxes, and which to are provided with teeth for moving the star- Wheels and picker-wheels to cause them to strike the teeth of the music-comb.

The object of the invention is to provide a strong and durable form of tooth for such :5 sheets; and for this purpose the invention consists of a tooth for note-sheets located opposite to and formed of the metal from an opening in said sheet and composed of an upright shoulder and an inclined back integral with each other and with the sheet, said shoulder being of approximately the same thickness as the sheet, while the inclined back is made of less thickness; and the invention consists, further, of a tooth of the form stated,

but in which the material of the back is hardened.

In the accompanying drawings, Figure 1 is an elevation of a note-sheet or music-disk embodying my invention. Fig. 2 is a larger sectional side elevation showing a portion of a note-sheet made in accordance with my invention in connection with the star-wheels and music-comb, the arrangement of which last-named parts may of course be varied.

Fig. 3 is a broken detail sectional view in perspective looking toward the top of the note-sheet, and Fig. a is a similar view looking toward the bottom of the note-sheet.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A indicates the body of my improved note-sheet or musicdisk, which is provided with the usual center opening Ct for receiving the center pin on which the disk rotates.

B indicates a plurality of teeth, which are struck up from the body A of the note-sheet and which are properly arranged upon the note-sheet, so as to result in the playing of the particular piece of music which is represented by the special arrangement of the teeth.

The note-sheet teeth B are bent up in the form of approximate acute angles, with slanting backs Z) and with perpendicular or approximately perpendicular shoulders Z), said backs Z) joining the body of the note-sheet at Z) and said shoulders Z) joining the body at b In striking up the angular teeth B openings C are left in the body of the note-sheet, and the teeth B are all bent away from the same side of the note-sheet, with their shoulders all presented in the same general direction.

The shoulders Z) of the teeth B are approximately of the same thickness as the body A of the note-sheet, while the inclined or slanting backs Z) are thinner than the thickness of the shoulders Z). In this way all the stock that is possible is left in the shoulders Z), which receive all of the wear byimpact against the star-wheels, while the thinner slanting backs Z) form a means of connection for the outer ends of the shoulders with the body A and brace and support the shoulders Z) sufliciently, so as to withstand all the shocks which are imparted to them by striking the star-wheels. The teeth B are thus formed integral with the body A of the note-sheet and are formed not only integral with the body A at one end, but the said teeth are integral with the body at both ends, so that it is very difficult to break the teeth away from the body. Furthermore, the backs of the teeth are somewhat harder or more highly tempered than the shoulders. This is due to the metal forming the backs being condensed in the process of forming the teeth, so that even with the backs thinner than the shoulders each tooth is approximately of the same strength throughout. The upper surface or face of the note-sheet is also perfectly smooth throughout and presents no objectionable corners, burs, or sharp edges at the portions out of which the teeth are struck up.

Teeth of the form described may be made of the requisite height for reliably actuating the teeth of the star-wheel of a music-box and are exceedingly strong and durable.

Having thus described my invention, what Patent, is-

l. A tooth for note-sheets, located opposite and formed of the metal from an opening in said sheet, and composed of an upright shoulder and an inclined back integral with each other and with the sheet, said shoulder being of approximately the samethickness as the body of the sheet, and said back of a less thickness, and said shoulder being connected at one end with the back and at the other end with the sheet, substantially as set forth.

2. A tooth for note-sheets, located opposite and formed of the-metal from an opening in said sheet, and composed of an upright shoulder and an inclined and hardened back integral with each' other and with the sheet, sub tantially as set forth.

"3'; A 'tooth for note-sheets, located opposite and formed of the metal from an opening in I said sheet,and composed of an upright shoulstantially as set forth.

4. 'A tooth for notesheets, located opposite and formed of the metal from an opening in go said sheet, and composed of an upright shoulder and an inclined and hardened back integral with each other and with the sheet, said shoulder being of approximately the same thickness as the body of the sheet, and said back of a less thickness, and said shoulder being connected at one end with the back and at the other end with the sheet, substantially as set forth.

5. A note-sheet having openings, and teeth located each opposite one of said openings, and formed of the metal of the same, and composed of an upright shoulder and an inclined back integral with each other and with the sheet, said shoulder being of approximately the same thickness as the body of the sheet, and said back of less thickness, and said shoulder being connected at one end with the back and at the other end with the sheet, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

JOSEPH NATTERER.
